To all ZU/I/OWY/ it 1nay00ncern;

Be it known that I, ARTHUR KLnINFnLDT, a citizen of the United States,residing at Hoboken, in the county of Hudson, in the State of NewJersey, have invented certain new and useful Improvements in Apparatusfor Charging Gas-Domes for Siphons, of which the following is aspecification, reference being had to the accompanying drawings, forminga part hereof.

This invention has for its object to provide an apparatus forconveniently and expeditiously charging with carbonic-acid gas the gasdomes or reservoirs which are attached to siphons or other receptaclesfor charged water for the purpose of maintaining pressure of gas in suchreceptacles and for recharging them as required.

The apparatus comprises in its most approved form means for supportingthe ordinary commercial cylinder in which compressed carbonic-acid gasis supplied, means for supporting the gas-dome to be filled, means foreffecting the necessary connection between the cylinder and the dome,and means for controlling the admission of gas to the dome.

Various features of the invention will be fully described hereinafterwith reference to the accompanying drawings, in which such an-apparatusis illustrated, and in which Figure 1 is a view in front elevation ofthe complete apparatus, partly broken out to save space. Fig. 2 is aview in side elevation of the same apparatus, partly broken out to showdetails of construction. Fig. 3 is a detail view, on a larger scale andpartly in section, illustrating further details of construction.

The apparatus illustrated in the accompanying drawings is designed foruse in places where the gas-domes are to be filled with gas, andtherefore comprises asuitable base a, having a seat I) for the ordinarycommercial container c for the compressed gas, and a pillar At asuitable height upon the pillar (Z is secured a frame a, which supportsthe working parts of the apparatus and holds the cylinder 0 firmly inposition, being provided with a detachable clamping member 6, whichcarries a set-screw e to impinge upon the cylinder. The frame 6 ispreferably held in adjustable position upon the pillar (Z, as by meansof a set-screw 6 in order to permit adjustment of the frame toaccommodate cylinders of different makes. Connection is made from thecylinder 0, as by a pipe 0, usual, with a regulating-valve f and thencethrough a stop-valve g, pipe 9, and depending nozzleg with the gas-dometo be filled, all of these parts being firmly supported upon the frame6. The gas-dome it is likewise supported by the frame a, but is movablewith respect thereto in order that communication may be conveniently andquickly established between the nozzle and the dome it, the latter beingprovided for this purpose with a nipple 71., which enters an elastic capg carried by the nozzle gfqwhereby when the dome is pressed upward atight joint is formed.

In a bracket 6*, depending from the frame 0, is mounted a cam-lever t,comprising a camnose t" and a suitable handle t Seated in the frame 0above the cam-lever '15 is a holder in, having a stem is, which isguided in and projects through the frame 0. This rests normally upon thehub of the cam-lever and is adapted to be raised by the movement of thecamnose"zl in order to effect a tight joint between the nipple it of thegas-dome h, which rests in the holder 7t and the nozzle 9 In order thatthe action of the cam-nose '11 may not rupture any of the parts, it isdesirable that such action should be cushioned, and for this purpose thecam-nose t" is arranged to act upon a plug if, which is seated upon aspring k in a recess in the stem 70. The spring 0 is sufliciently stiflto insure a tight joint between the dome it and the nozzle gibut yieldsupon excess of pressure to prevent the breakage of connected parts. Forthe purpose of insuring the correct position of the holder Z: with thedome it thereon a rod 1 is secured to the holder It, as by a set-screwZ, which per.- mits adjustment of the rod and moves freely in an opening0, formed therefor in the frame a. The rod Z also serves as a supportfor an adjustable guide-arm m, by means of which the operator mayquickly and exactly correct the position of the siphon-tube a, which isusually secured to the dome it by means of an elastic sleeve 0. As iswell understood, it is necessary that the tube 02/ shall be vertical inthe siphon in order that the contents of the siphon may be completelydischarged. The flexible sleeve 0, by which the tube is connected to thedome, permits the tube to get out of position somewhat at times; but thearm m furnishes a guide by which the operator can quickly aline the tubepreparatory to replacing the dome on the siphon.

In order to permit the rapid manipulation of the apparatus and toprevent waste of gas,

it is desirable that the opening and closing of the stop-cock g beeffected automatically. Accordingly, to the stem g of the stop-cock issecured an arm g A link p connects the arm g with one end of a lever p,pivoted upon a bracket 6 of the frame 6, the other end of said leverstanding in the path of the cam-lever 2', so that as the latter isoperated to raise the holder 70, and with it the gas-dome it toestablish connection with the gas-supply, the valvestem 9 is oscillatedto open the valve and permit the flow of gas. The valve remains openwhile the gas-dome is in its elevated position, and as soon as thelatter is lowered to permit its removal a spring q, connected to the armand to the frame 6, operates to close the valve. Connection between thelink p and the lever 19 is preferably elfected by nuts p carried by thelink on opposite sides of the lever p, so that adjustment can beefiected to insure the opening of the valve at the proper instant.

As represented in Fig. 3 of the drawings and as fully described inLetters Patent of the United States No. 706,423, granted August 5, 1902,to me the wall of the dome h is provided with a valve 9, adapted toregulate the passage of gas from the dome to the siphon and controlledby the handle 9, which also controls the valve 8, which regulates theoutflow of liquid from the siphon.

Itwill now be understood that in the use of the apparatus the dome to befilled is. placed in the holder A} while the latter is in its lowermostposition. As the holder is raised by the action of the cam-nose t" atight joint between the gas-dome and the gas-supply is effected, and atthe same time the gas-cock is opened to permit the flow of gas. Whilethis is taking place the operator can correct the position of thesiphon-tube n by bringing it into line with the end of the guide-arm m.

'VVhen the dome is fully charged, the handle is raised, thus loweringthe holder is and permitting the gas-dome to be withdrawn,

while at the same time the gas-cock g is closed.
